The Curse of The Werewolf (Werewolf! OC x RWBY)

Onyx was a boy raised by wolves, his father didn't want him because of his faunus appearance. He has wolf ears and a tail... he doesn't speak much because of his lack of vocabulary, but he's otherwise timid... until night when his feral instincts kick in causing fur to grow all over his body, and his control is lost...
